Test items used to survey the attainment of science process skills in a representative sample of 11 year olds in Britain were analyzed to determine the level of demand, in Piagetian terms, made by each item. It was found that: the level of cognitive demand was a reliable predictor of the limiting difficulty of an item; that the difference between potential difficulty as measured by supposed demand level and the actual difficulty encountered by subjects was revealing of areas in the curriculum where further effort in teacher education and curriculum development would be profitable; and that there was some evidence for an inherent hierarchy of process skills. 相似文献

Metacognition's roles in self-regulation of cognitive tactics and strategies is explored in relation to five sites where individual difference factors are likely to be observed and affect performance: domain knowledge, knowledge of tactics and strategies, performance of tactics and strategies, regulation of tactics and strategies, and global dispositions. Though the current literature is sparse, tentative hypotheses about kinds of individual differences and their impact are proposed. Directions for future research are noted concerning the need for more sophisticated metacognitively-based models of SRL as a complex collection of individual differences, and some suggestions are made about methodologies for investigating complex, metacognitively regulated approaches to learning. 相似文献

The four FRBR user tasks have become widely accepted as functions of the library catalog, but there have been only sporadic discussions concerning their validity and sufficiency, despite their modification in the models subsequently presented in the FRAD, FRSAD, and draft FRBR-LRM reports. This article presents a critique of the four variant sets of user tasks, and proposes an extended set of six generic end-user tasks, applicable to both bibliographic and authority data: locate, collocate, connect, identify, select, and obtain. The article also outlines their interrelationships and suggests those tasks that may be particularly well supported by professional cataloging. 相似文献

Robots are becoming more commonly used in libraries. A robot that does shelf reading and reports the results to human staff is one example of a practical use of robotics in a library. Others have been used to retrieve large items such as boxes, but identifying and picking up small and varied objects such as books is still on the edge of what can be done. Devices using artificial intelligence can act as guides, or in some cases, as personal assistants for library customers. Some are answering questions and learning as they go. If robots can perform library work effectively and more cheaply than humans it is inevitable they will be more widely used. 相似文献

The present article reports results of a real‐world effectiveness trial conducted in Denmark with six thousand four hundred eighty‐three 3‐ to 6‐year‐olds designed to improve children's language and preliteracy skills. Children in 144 child cares were assigned to a control condition or one of three planned variations of a 20‐week storybook‐based intervention: a base intervention and two enhanced versions featuring extended professional development for educators or a home‐based program for parents. Pre‐ to posttest comparisons revealed a significant impact of all three interventions for preliteracy skills (= .21–.27) but not language skills (d = .04–.16), with little differentiation among the three variations. Fidelity, indexed by number of lessons delivered, was a significant predictor of most outcomes. Implications for real‐world research and practice are considered. 相似文献

This paper discusses the role of ubiquitous and handheld computers in education. CILT contributions in this area are summarized, the Ubiquitous Computing sessions at the CILT2000 Conference are described, and future directions are highlighted. It is posited that handheld computers have the potential to reduce the digital divide, while also providing for a wide array of learning activities that can benefit all students. 相似文献

Analysis and modeling of time to event data have been traditionally associated with nonparametric, semiparametric, or parametric statistical frameworks. Recent advances in latent variable modeling have additionally provided unique analytic opportunities to methodologists and substantive researchers interested in survival time modeling. As a consequence, discrete time survival analyses can now be readily carried out using latent variable modeling, an approach that offers substantively important extensions to conventional survival models. Using data from the Health and Retirement Study, the discussed approach is applied to the study of the increasingly prominent vascular depression hypothesis in gerontology, geriatrics, and aging research, allowing examination of the unique predictive power of depression with respect to time to stroke in middle-aged and older adults. 相似文献

The aim of the present study was to build on John Greer’s systematic set of studies concerned with teenage beliefs and values conducted among samples of sixth form students attending County and Protestant voluntary schools in Northern Ireland in 1968, 1978 and 1988. The present study replicated the earlier surveys for a further time in 1998. The results provide a unique snapshot of the persistence of religious affiliation, belief and practice across the latter part of the twentieth century in a nation which has continued to resist the secularisation process so eroding the place of religion in the neighbouring nations of England, Wales and Scotland. 相似文献
